Physics-Power in AC Circuits
NEET Physics Power in AC Circuits Match the Following Question
Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Average power in an inductor | (i) Zero |
| (b) Average power in a resistor | (ii) Non-zero |
| (c) Power factor in RLC circuit | (iii) Cosine of phase angle |
| (d) Reactive power in AC circuit | (iv) Does not contribute to work |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iv, b-iii, c-i, d-ii
D
a-iii, b-iv, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
The average power in an inductor is zero because it does not consume power over a complete cycle, while a resistor has non-zero average power. The power factor is the cosine of the phase angle in an RLC circuit, and reactive power does not contribute to work.
